Debugger

7.1 Introduction

The design of the Tornado debugger, CrossWind, combines the best features of graphical and command-line debugging interfaces. The most common debugging activities, such as setting breakpoints and controlling program execution, are available through convenient point-and-click interfaces. Similarly, program listings and data-inspection windows provide an immediate visual context for the crucial portions of your application.

For more complex or unpredictable debugging needs, a command-line interface gives you full access to a wealth of specialized debugging commands. You can extend or automate command-line debugger interactions in the following complementary ways:

A Tcl scripting interface allows you to develop custom debugger commands.

You can extend the point-and-click interface, defining new buttons that attach to whatever debugging commands (including your own debugger scripts) you use most frequently.

The underlying debugging engine is an enhanced version of GDB, the portable symbolic debugger from the Free Software Foundation (FSF). For full documentation of the GDB commands, see Debugging with GDB.
